thermida is used a lot in coding it seems
go to your firewall/anti-virus program and set the hack that causes the thermida errors as an exclusion
try to use a slower speed..somewhere around 1.25-1.35ish.
if you lag bad dont use it at all

a little more detail as to what happens would be helpful
what does the error say?
does the game just crash or freeze?
does turning the chams on cause the problem to happen?
do you go through 1 game then it crashes/errors?
